Title: Improvements relating to electric protective devices for neon signs
IPC: H01G2/00
Filed: 1953-05-12
Abstract: 739,197. Protective cut-out arrangements. WALTERS, A., [Representative of WALTERS, A.]. May 5, 1964 [May 12, 1953], No. 13203/53. Class 38 (5). A condenser a is arranged in parallel with spring contacts c which are held apart by an insulator d which will collapse when exposed to excessive heat. The device is intended for connection across a neon tube so that if the tube develops a fault, the voltage across the condenser causes a spark between the contacts c which generates sufficient heat to melt the insulator, thus enabling the contacts c to close and short the faulty tube. The contacts may comprise coil springs mounted on the condenser as shown, or spring blades, or may be carried on spring-loaded levers. The insulator may be of wax or polythene.

Abstract: 753,215. Vehicle lamps. CIBIE, P. May 27, 1952 [May 28, 1951 ; March 31, 1952; May 12, 1952], No. 13444/52. Class 75(2). In a light projector giving an anti-dazzle beam and comprising a parabolic reflector and a light source such as an electric bulb having at least one screened filament, optical means adapted to cause solely horizontal divergence of some or all of the rays are interposed across a portion of the beam and are bounded laterally by two lines OL, OM, Fig. 5, on the same side of the horizontal diametral plane of the projector and on opposite sides of the vertical and intersecting in the optical axis O of the projector; and the sector shaped areas a bounded by the lines OL, OM and the diametral plane are plane or adapted to cause purely horizontal deviation and/or limited divergence of some or all of the rays which pass therethrough. The projector is arranged as a vehicle headlight and produces a beam which has a transverse section of the form shown hatched in Fig. 2 and which is directed below a cut-off plane slightly inclined longitudinally below the horizontal diametral plane of the projector. The optical means are located above the diametral plane in the case of a projector giving a converging beam and below the diametral plane in the case of a projector giving a diverging beam. The two lines OL, OM bounding the optical means laterally are preferably arranged at the same inclinations to the horizontal as the projections from the projector of the sides of the road on to a vertical plane. The optical means may be shaped as a sector of a circle or a sector which is centrally curtailed by a circular arc or laterally curtailed by two vertical lines or the bounding lines may comprise either two stepped lines substantially radial of the glass and a straight horizontal line or curved lines substantially defining a triangle. The optical means are constituted by diverging ribs, Fig. 17, formed on the inner or outer surface of the closing glass and located in the plane passing through the edge of the reflector. The ribs on each side of the vertical median plane deviate the rays towards that plane and the two faces of each rib converge in such manner that each rib produces equal mean deviation of the rays passing therethrough. A portion of the closing glass having parallel faces may be interposed between adjacent ribs. The sector shaped areas a formed between the lines OL, OM and the horizontal diameter may be provided with ribs adapted to deviate horizontally and diverge slightly the light rays so that the zones of illumination produced on the road by these rays are slightly shifted toward the axis of the projector.

Abstract: 417,140. Electric horns. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Delco-Remy Corporation ; 329, E. 1st Street, Dayton, Ohio, U.S.A.) May 9, 1933, No. 13464. [Class 13.] In a sound signal device the vibrating diaphragm is secured at its periphery to a cooperating apertured collar member the area of contact therewith enlarging as the diaphragm approaches said member until the air space there-between is substantially eliminated. In one embodiment the diaphragm 40, Fig. 1, is corrugated and clamped to the magnet framework 21 by an apertured collar 50 whose inner surface is shaped so as to form a gradually increasing air-space between it and the diaphragm from periphery to centre, the aperture at which communicates with a horn 60. The diaphragm 40 and laminated armature 36 with spacing washer 37 are threaded on a rod 33 passing through the centre of the laminated field magnet 22 and working in a bearing sleeve 34, a projection on the rear end of the rod 33 operating the contact breaker. In its extreme position the diaphragm expels substantially all the air between it and the adjacent surface of the collar 50. A housing 47 covers the operating mechanism and is held in position by a flange held by some of the diaphragm clamping screws 45. In a modification, Fig. 3, the flat diaphragm 40<a> co-operates with a collar 50<a> of composite form the middle annular section 50b being adjustable to and from the diaphragm by being threaded into an outer diaphragm-clamping portion 56<a> and fixed after adjustment by a plate 62 and screw 63. The portion 50b receives a central threaded collar 53<a> secured to the trumpet 60 and fixed by a lock-nut 61. In a further embodiment the armature 36, Fig. 4, is behind the magnet 20 and is supported on a cantilever spring 70, loading washers 71 being provided for synchronizing the armature and diaphragm periods. The collar 50 is associated with a cover plate 72 providing a spiral passageway 74 between the diaphragm and horn 60. The members 50 and 72 may be made in two sizes to provide different lengths of air columns. A hemispherical cover 47 is screwed at its centre to a stirrup 75 secured to the framework of the device.

Abstract: 623,863. Machinery safety devices. VICKERSARMSTRONGS, Ltd., and NASMITH, J. I. May 20, 1947, No. 13566. [Class 80 (iv)] In a machine for feeding strip material such as ornamental or protective layers of adhesive paper, onto workpieces, such as cartons or cardboard boxes; the tension of the strip of material 3 controls the operation of a cutting knife 1 for automatically cutting the material off to length. The knife blade 1 which effects its working stroke under spring pressure is carried on an arm 2 rotating on pivots 21 and cooperates with a fixed blade 10. The strip material 3 passes through guide rods 8, 9 on a pivoted frame 6 and when there is no tension on the strip this frame assumes the position shown so an abutment 11 thereon comes under a stop arm 5 bn the knife arm 2 to prevent its cutting stroke. When the strip is tensioned by a manual feeding operation by the operator on to the workpiece which removes his hands from the cutting zone the frame 6 is lifted and the abutment 11 is moved out of the path of the stop arm 5 to allow the cutting stroke of the knife 1 to be effected, the frame 6 being raised further in the process by the engagement of the arm 2 therewith.

Title: Improvement in surface condensers
IPC: F28B1/02
Filed: 1925-05-27
Abstract: 241,516. Ingersoll-Rand Co., (Assignees of Bancel, P. A.). Oct. 15, 1924, [Convention date]. Surface condensers.-In surface condensers in which the cooling tubes D pass across the steam space, and in which therefore the inlet ends E of the tubes are cooler and have greater condensing capacity than the outlet ends F, the flow of steam from the inlet B is arranged so that the steam penetrates to the same depth at both ends of the condenser. This involves passage of more steam over the inlet ends E and is effected by restricting the flow of steam at the outlet ends F by inserting a perforated partition among them or by bunching the upper rows of tubes together. The Specification as open to inspection under Sect. 91 (3) (a) describes also that an inclined partition projecting into the steam inlet B may be attached to the tube-supporting plate K, a valve being arranged in the narrow portion leading to the outlet and F if desired. The two compartments formed by the plate K may have separate connections to the vacuum pump and different degrees of vacuum be maintained in each compartment. Each compartment may be divided by additional tube-supporting plates and perforated plates be inserted across the outlet ends to distribute the steam in the separate compartments. The steam passing to the two sections of the condenser may be apportioned by a curved extension of the tube-supporting plate passing upwards to the turbine runner and dividing the turbine casing. The steam inlet and condensate outlet may be arranged nearer to the inlet ends E of the cooling tubes than to the outlet ends F. This subject-matter does not appear in the Specification as accepted.
